我有一个复选框列表,我希望在选中时切换内容。我用jQuery写了它,但我想以某种方式优化我的代码,我不必为每个复选框编写一个函数。
$(document).ready(function() {
$("#purpose-1").click(function() {
$("#purpose-detail-1").toggle(this.checked);
}).triggerHandler('click');
$("#purpose-2").click(function() {
$("#purpose-detail-2").toggle(this.checked);
}).triggerHandler('click');
$("#purpose-3").click(function() {
$("#purpose-detail-3").toggle(this.checked);
}).triggerHandler('click');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>
<input type="checkbox" id="purpose-1">Exhibition
<ul id="purpose-detail-1">
<li>
<div>Title:</div>
<div>
<input type="text">
</div>
</li>
<li>
<div>Opening Date:</div>
<div>
<input type="text">
</div>
</li>
</ul>
</li>
<li>
<input type="checkbox" id="purpose-2">Publication
<ul id="purpose-detail-2">
<li>
<div>Title:</div>
<div>
<input type="text">
</div>
</li>
</ul>
</li>
<li>
<input type="checkbox" id="purpose-3">Event
<ul id="purpose-detail-3">
<li>
<div>Title:</div>
<div>
<input type="text">
</div>
</li>
<li>
<div>Event Date:</div>
<div>
<input type="text">
</div>
</li>
<li>
<div>Event Time:</div>
<div>
<input type="text">
</div>
</li>
</ul>
</li>
</ul>

我会使用课程并使用next()
ul
$(document).ready(function() {
$(".my-ul").hide();
$(".my-checkbox").click(function() {
// in case the 'ul' is next to the checkbox:
// $(this).next('ul').slideToggle(this.checked);
// in case the 'ul' is in the same element but not next to the checkox:
$(this).parents('li').find('ul').slideToggle(this.checked);
// or maybe even better:
// $(this).closest('li').find('ul').slideToggle(this.checked);
});
});

使用课程:
<input type="checkbox" class="purpose-checkbox" id="purpose-1">Exhibition
<ul class="purpose-detail" id="purpose-detail-1">
...
</ul>
然后在jQuery中:
$(".purpose").click(function() { // We choose elements with purpose class
var $this = $(this); // The purpose checkbox clicked
var purpose_detail = $(".purpose-detail", $this ); // Element with purpose-detail class inside the clicked checkbox
purpose_detail.toggle( $this.prop("checked") );
});
